Hi likhith,  
CMS error 305 means invalid text mode parameter, are you sending some special character?

It works quite well in my test, below my log:

```
AT+CMGF?
+CMGF: 0

OK
AT+CMGF=1
OK
AT+CSCS?
+CSCS: "IRA"

OK
AT+CSCS="GSM"
OK
AT+CPMS?
+CPMS: "SM",0,40,"SM",0,40,"SM",0,40

OK
AT+CSMP?
+CSMP: ,,0,0

OK
AT+CMGS="91234567"
> testing <ctrl-z>

+CMGS: 1

OK
AT+CMGS="91234567"
> HI <ctrl-z>

+CMGS: 2

OK

```

As you are using WP7608, can you also try using the console tool “cm” to send SMS and see does it work? i.e.

> cm sms send 7259485968 HI

Thx

Thanks

Would you please try below and capture the info?

Try to send using PDU, i.e. below for the number in your log:

```
AT!GSTATUS?
AT+CMGF=0
AT+CMGS=16
> 01000AA12795849586000004D4F29C0E <ctrl-z>

```

And to get debug legato log

```
cm radio
log level debug
logread -f
cm sms send 7259485968 hello

```

Thanks!
